How a World Engine Works

A World Engine is a fully realized universe made playable. You don't watch it — you live in it. Here's the shape of it.

01
Build
Shape your character, set the tone, bring your own lore. The world is already built — you decide who you are in it.
02
Inhabit
Step inside and drive the story. The narrator reacts, the cast remembers, and the world holds to its own rules.
03
Live It
Every choice has weight and consequence. Nothing resets, nothing forgets. The story is yours alone.
All you need is your own AI key — most messages cost less than a cent, and everything runs right in your browser. No install, no download. Read the FAQ →

Don't see your world?

Every world here was built from scratch. Yours can be too — bring your universe, your IP, your vision, and we'll build the engine that brings it to life.
